DETAILED DESCRIPTION

[0014] like Figure 1-Figure 2 As shown, the utility model is described in detail. For the convenience of description, the directions mentioned below are defined as follows: the up, down, left, right, front and back directions mentioned below are the same as Figure 1The up, down, left, right, front and back directions of the projection relationship itself are consistent. The utility model is a polypropylene cap assembly device, including a bracket 17, a first conveyor 11 is provided at the bottom of the bracket 17, and second conveyors 13 are provided on both sides of the first conveyor 11. The first conveyor 11 and the second conveyor 13 are existing technologies and can be driven by a motor to perform the conveying function. A plurality of bottles 12 are arranged on the first conveyor 11, and a plurality of polypropylene caps 14 are arranged on the second conveyor 13. The polypropylene cap 14 is located on one side of the bottle 12, and a robot assembly is provided in the bracket 17.

[0015] Advantageously, the manipulator assembly includes a movable frame 23 that slides within the bracket 17, two rotating electric claws 15 are provided at the bottom of the movable frame 23, a sliding structure that drives the movable frame 23 to slide is provided in the box 19, and a lifting structure that drives the rotating electric claws 15 to rise and fall is provided in the movable frame 23. After the rotating electric claws 15 clamp the polypropylene cap 14, the sliding structure is used to move to the upper side of the bottle 12, and then the lifting structure and the rotating electric claws 15 are used in conjunction with each other to rotate the polypropylene cap 14 and then connect and fix it with the bottle 12 through threaded connection, so that the polypropylene cap 14 is installed on the upper side of the bottle 12, thereby realizing the assembly function.

[0016] Advantageously, the rotary electric gripper 15 is prior art, and is an advanced industrial robot end effector that combines the functionality of a traditional gripper with rotational motion capabilities; such devices are typically designed for use in automated production lines to more efficiently and accurately grasp, carry, and place objects; the following are some key features of the rotary electric gripper: Opening and Closing and Rotation: The rotary electric gripper can not only open and close like a traditional gripper to grasp or release the workpiece, but can also rotate while maintaining its grip; this allows for positioning adjustments of the grasped object.

[0017] Advantageously, the sliding structure includes a plurality of guide rods 35 disposed in the box body 19 , and sliding seats 36 are provided on both sides of the movable frame 23 , the sliding seats 36 are slidably connected to the guide rods 35 , and a pushing component is provided on one side of the box body 19 to drive the movable frame 23 to push.

[0018] Advantageously, the pushing component includes a pushing cylinder 18 provided on one side of the box body 19 , a push rod of the pushing cylinder 18 passes through the box body 19 , and the push rod of the pushing cylinder 18 is fixedly connected with a matching seat 37 on one side of the moving frame 23 .

[0019] Beneficially, the lifting structure includes a motor 22 arranged at the top of the mobile frame 23, a threaded shaft 21 is provided on one side of the motor 22 for power connection, the threaded shaft 21 is rotatably connected to the mobile frame 23, a lifting plate 33 is provided for sliding inside the mobile frame 23, a plurality of internal threaded sleeves 31 are provided inside the lifting plate 33, the internal threaded sleeves 31 are threadedly connected to the threaded shaft 21, a through hole 32 is provided at the bottom of the mobile frame 23, a fixed shaft 34 is provided at the bottom of the lifting plate 33, the fixed shaft 34 passes through the through hole 32, and the fixed shaft 34 is fixedly connected to the rotating electric claw 15.

[0020] The device is equipped with two rotating electric claws 15, which can form a working rhythm with the first conveyor 11 and the second conveyor 13 on the first conveyor 11 and the second conveyor 13, so as to take the polypropylene cap 14 on the second conveyor 13 and place it on the upper side of the bottle 12, and then rotate the polypropylene cap 14 and lock it to the upper side of the bottle 12.

[0021] When the device is working, the push cylinder 18 can drive the matching seat 37 and the moving frame 23 to slide along the guide rod 35 after working.

[0022] After the motor 22 starts working, it drives the threaded shaft 21 to rotate. That is, after the threaded shaft 21 is threadedly connected with the internal threaded sleeve 31, the lifting plate 33, the fixed shaft 34 and the rotating electric claw 15 can be moved up and down.

[0023] After gripping the polypropylene cap 14 , the rotating electric claw 15 can rotate after gripping, thereby achieving rotational locking of the polypropylene cap 14 and the bottle 12 .

[0024] like Figure 1 As shown, the rotating electric claw 15 located at the rear side cooperates with the motor 22 to work after it starts working, so that the rotating electric claw 15 can drive the polypropylene cap 14 to rotate and then move downward to screw lock with the bottle 12. The friction between the first conveyor 11 and the bottle 12 is relatively large, and the bottle 12 will not rotate during the screwing process of the polypropylene cap 14. After it is screwed into place, the motor 22 drives the threaded shaft 21 to rotate again, so that the lifting plate 33 drives the rotating electric claw 15 on its lower side to move to the upper side. The rotating electric claw 15 needs to release its claws before moving.

[0025] At the same time, the rotating electric claw 15 on the front side clamps the polypropylene cover 14 on the second conveyor 13 on the front side and moves it to the upper side.

[0026] After this, the second conveyor 13 and the first conveyor 11 work for just the distance of one working step, so that the polypropylene cap 14 and the bottle 12 without the polypropylene cap 14 are positioned under the rotating electric claw 15 again.

[0027] After the push cylinder 18 works, it drives the movable frame 23 to move backward, so that the front rotating electric claw 15 is located on the upper side of the bottle 12 without the polypropylene cover 14 installed, and then the rear rotating electric claw 15 is located above the polypropylene cover 14 on the rear second conveyor 13.

[0028] After this, the rotary electric claw 15 of the front side is rotated downwards to screw the polypropylene cover 14 in its claw onto the knife bottle 12, and then the rotary electric claw 15 of the rear side is downwardly clamped with the polypropylene cover 14 on the rear side second conveyor 13 and reset upwards.

[0029] After the front rotating electric claw 15 is twisted, it is also reset upwards, and then the first conveyor 11 and the second conveyor 13 are allowed to run one step again, and then the above-mentioned work content is repeated.

[0030] It is only necessary to place the polypropylene caps 14 on the second conveyor 13 at intervals and place the bottles 12 on the first conveyor 11.

[0031] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention; therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
